The validation process of truss model with joint eccentricities
Nowadays, due to the technological reasons in modern lightweight steel trusses, fabricated from cold-formed sections, positive eccentricities appear in the truss nodes, to induce additional forces truss chords. In order to account for the real load-carrying capacity of truss node area the steel structure research was conducted in scale 1:1. As a result of experimental research, the forms of deformation and strains of the walls of the chord made of the hat section in the area of the analyzed joint was determined. The experimental results from the basis for the numerical model validation was presented in the paper.
